Rails - Jan 2007 - How to change the menu depending on the controller/method?

Hello,

I''m still dtarting with ruby on rails. And I''m trying to have
a menu
depending on the current controller/method.

Here is what I was thinking of (please tell me if there''s a better way
to do it):

I have a database with menu_groups (corresponding to controllers) and
menu_elements(corresponding to methods). Each menu_element belongs to
one menu_group.

I created a class Menu where I get all the menu_groups and
menu_elements, and where I have the active controller and method.

"
class Menu
  attr_reader :menu_groups
  attr_reader :menu_group_active
  attr_reader :menu_elements
  attr_reader :menu_element_active
  def initialize
    current_url_elements=request_uri().split("/")

    @menu_groups << MenuGroup.find(:name,:order => "id")
    @menu_group_active = controller.controller_name
    @menu_elements << MenuElement.find(:all,:order =>
"menu_group_id
id")
    @menu_elements_active = current_url_elements[-1]
  end
end
"

Then, thanks to the attributes of this class I''ll be able in my layout
to make the difference between active and non active groups/elements.


The problem here is that I don''t know how to get the url into a
variable...


If my method is good, can you please tell me how to make it works?
If not, can you show me the right way to do this??

Thanks a lot

Best regards,

Matthieu

I add something:

I have one common layout for all my controllers.

Unless I am missing something...Make layouts out of your menus then do
something like this

In your controllers or even your application.rb
layout :select_layout

then this method at the end of your controller
private
  def select_layout
    [''action_name1'',
''action_name2''].include?(action_name) ? "layout1"
: "layout2"
  end

Storing references to a menu in a DB seems wrong.

Help that helps.

Do you mean, I have to do one layout for every situation my menu will be 
in (=the number of method I''ll have)??
It seems a lot to me and maybe I''m wrong but it would induce a lot of 
redundency, no?

No - you make a layout for the menu - how many menus do you have? Your
menu should retain a consistant look across most of your
controllers/actions - unless I am not understanding something. I don''t
understand what you mean by "the situation my menu will be in (=the
number of method I''ll have)"  If you mean, for example,  that you
want
the "comments" menu item to be a different color when you are
performing that action then use CSS and helper methods like
link_to_unless_current amongst others.

It seems like you might want to read some ofthe multiple of books this
list preaches about.

  def select_layout
> >     [''action_name1'',
''action_name2''].include?(action_name) ? "layout1"
> > : "layout2"
> >   endwhat does ''action_name'' represent ?
action_name is the name of the action that should use layout1.
